SUSPICIOUSLY PRECISE FLOATS, OR, HOW I GOT CLAUDE'S REAL LIMITS

This dev reverse-engineered Claude's hidden usage limits and internal credit system by analyzing unrounded float values from the API. Findings show the 5x subscription plan has amazing value, providing much more usage (up to 8 times weekly) than advertised, while the 20x plan is less efficient for weekly tasks.
